Background: Immune and vascular ageing are proposed risk factors for giant cell arteritis (GCA). Data on the impact of age at diagnosis of GCA on the clinical presentation and course of the disease are scarce.
Methods: Patients with GCA followed at referral centres within the Italian Society of Rheumatology Vasculitis Study Group were enrolled up to November 2021.
Objectives: Interstitial lung disease (ILD) has been described as a possible pulmonary involvement in antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV), mainly granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). Aim of this cross-sectional Italian national study was to describe demographic, clinical and serological profile of ILD related to MPA and GPA and investigate possible correlations between radiologic patterns of ILD and vasculitis features.
Methods: We enrolled 95 consecutive patients with AAV-ILD, 56 affected by MPA (58.
